Important Notes

•This calculator provides estimates only and does not constitute legal or tax advice. Please consult a qualified real estate lawyer or tax professional before making financial decisions.
•Results are based on legislation as of April 2026. Tax rules may change. This tool applies to Ontario new home purchases only.
•Your agreement purchase price typically includes the baseline $24,000 provincial rebate, which is assigned to the builder. The rebate amounts shown reflect the total program value, and the “Claimable from CRA” amount is what you can recover beyond what’s already in your price.
•The Ontario provincial First-Time Home Buyer HST rebate (up to $80,000) has been announced but has not yet received Royal Assent. Buyers should not make final financial plans based on this component until it is legislated.
•The expanded HST rebate for all buyers (April 1, 2026 – March 31, 2027) was announced in the Ontario 2026 Budget but is subject to federal legislation. Implementation details have not yet been released.
